My daughter keeps bringing up how we don’t have enough money for food.

My daughter (10f) and I (29f) just moved into a new apartment. This is the first time she and I have lived alone since she was born. I’ve always had a roommate or my ex living with us so this is an amazing new part of our lives and we are so happy it’s just us two and our pets. But ever since we moved she has this idea that we don’t have enough money for food. She’ll come to me and say she’s hungry and I’ll offer to cook her something or ask her if she’s craving a specific thing that I can order for her and she’ll tell me “ no mom it’s to expensive”. The thing is we are very financially stable. I’ve tried talking to her about it and I have a meeting set up with a new therapist for her. But I have no idea where she is getting this idea and I’m worried if it goes on to long she’ll develop a bad relationship with food. Has anyone else every gone through something like this and if so how did you handle it?
